Identification:
This species is a subspecies of the red-spotted snake (Oreocryptophis porphyraceus). It is of average size, typically measuring between 1 and 1.2 meters in length. The head is elongated and distinct from the neck. The face is of moderate size, with round pupils. The upper lip consists of 8 scales, with 2 scales bordering the eyes. The scales encircling the mid-body are arranged in 19 rows and are smooth. The ventral scales are rounded, while the anal plate is divided into two. Subcaudal scales are arranged in two rows. A thin, black line extends from the junction of the two prefrontal scales, running along the midline of the head to the posterior of the two parietal scales. The throat and belly are pale yellow. The dorsal surface is reddish-brown, with two thin, black parallel lines extending from the eyes to the tip of the tail. Young individuals have a series of large, nearly circular, grayish-brown dorsal blotches with light edges. These blotches become less distinct towards the posterior of the body.
Biology and Ecology:
This species is commonly found along forest edges near streams and rivers in mountainous regions. Its primary diet consists of amphibians and small rodents. Its distribution includes national parks in the eastern and northwestern regions of Vietnam, such as Lạng Sơn, Thái Nguyên, Vĩnh Phúc, and Quảng Bình. The species has also been recorded in Konkakinh National Park in Gia Lai province.
Value:
This snake species has attractive markings and is non-venomous, leading to its frequent capture for the pet trade in Vietnam and internationally. It is a rare species that requires conservation efforts.
